If you’ve seen the movie “Clash of the Titans” or remember the old TV series “Gumby,” you’ve seen a kind of animation called “stop motion.” In stop-motion, you make a movie frame by frame, moving the objects a tiny fraction each time. There’s new software out for Mac users who want to make their own animations.

“iStopMotion 3.6,” $50 from Boinx Software, now works with DSLR cameras from Nikon and Canon. It now has a feature called “onion skinning” which allows animators to make tiny adjustments before capturing a frame. Other features let animators use another movie as a guide to improve animation, make a scene look like a miniature, or put an actor into an animated scene. The “Stop Motion Handbook,” by Craig Lauridsen, $25, shows you how to do it.
